But "readiness" is seemingly defined by how many bootees/babygros/cute ickle wotsits you can purchase before the baby's born when you'd do better to read up about oh, I don't know, birthing and feeding?
So don't worry that you haven't colour-coordinated every washed and ironed in anticipation outfit/bought 58 squillion muslin squares to match said outfits.
And no, you don't need bottles and breast pumps. If you DO need them, you (or preferably someone else) can get them when the baby's born. Research what you want. But don't part with your cash. Otherwise it's just a waste of money, right?
